Hello Pirate ... what is your idea of inexpensive? You could try Airbnb and/or Vrbo, but for a really nice place during the winter months with a pool the average monthly rental will run about $2,500. Of course, this all depends on what you are looking for and where. A basic two person studio apartment with a pool in the Oyster Pond area could go as low as $1,200 a month, but it won't be on the water. In you are thinking more of the Orient Bay area, try Mont Vernon on Airbnb, but the rates here are likely to start at $2,000 or more per month. And, you have to be absolutely sure they are 'ready-to-go' and still not in need of repairs. That would be a huge risk to put a deposit on a place scheduled for repairs. Just my two cents.
